31. Architectures, design methodologies, and service composition techniques for Grid job and resource management
Sammanfattning : The field of Grid computing has in recent years emerged and been established as an enabling technology for a range of computational eScience applications. The use of Grid technology allows researchers and industry experts to address problems too large to efficiently study using conventional computing technology, and enables new applications and collaboration models.

32. Have a fling with your neighbour, you might be less related
Sammanfattning : Major threats to biodiversity and ecosystem persistence are fragmentation of habitats and declining population sizes. For conservation biologists to understand the consequences of declining populations for the long term persistence and recovery of species worldwide, it is important to know and understand the underlying causes of potential threats, such as the depletion of genetic diversity, which is important for populations to be able to adapt and prevail in a changing environment.

33. Disturbances in food webs : Importance of species interactions from an ecological and evolutionary perspective
Sammanfattning : Biodiversity loss is occurring globally at an unprecedented pace. This is not only followed by ethical concerns; it also affects all levels of an ecosystem, with wide-spread implications for ecosystem functioning, services and human well-being. LÄS MER
34. The Arthropod Assemblage of the Upper Devonian Strud locality and its Ecology
Sammanfattning : The Devonian (419-359 million years ago) is the geological period when the terrestrial biota fully established. Early representatives from a terrestrial and continental aquatic biota have previously been reported from the Upper Devonian (Famennian) Strud quarry in Belgium, in the shape of seed-bearing plants and vertebrates (fish and early tetrapods).

35. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia
Sammanfattning : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. LÄS MER
